Well thanks. Guess I got my answer.
But my mind will never stop with more questions. Why are some stalks skinny, and others, fat? Like with the PF tek, they're commonly fat stalks. But with this grass seed tek, I believe the word used was "spindly". I'm not still on the old debate, I'm just asking why there is a difference in size. Because I find it all very interesting.

Long post time!
Mostly, differences in macroscopic appearances are due to genetics. Conditions do play a hand though. Most mushroom species do grow too thin under extreme CO2 conditions, and many grow trailer than they otherwise would too, resulting in something that's clearly not their ideal form. Blue Oyster is particularly bad about this, for instance. But Cubensis is not. As almost all of our Cubensis teks take advantage of, they are highly CO2 tolerant. Under conditions that other species wouldn't fruit properly or at all, Cubensis fruits in ideal fashion, and can even thrive. It takes a some real stifling to get them to deform.
Lots of people on here think in terms of CO2 retention/release, forgetting that the initial determining factor, in fact the reason for the topic at all, is CO2 PRODUCTION. Mycelium breathe out CO2. The main thing that causes excess is a giant substrate or substrates that produce increased amounts of mycelium, of which bulk substrates do both, such as in mono tubs which also confine their substrates to a small proportion of only overhead space for air. This is why there are whole threads, very active ones at that, dedicated to instructing how to 'tune' the tubs to get enough air, such as the one in FrankHorrigan's tek list which is the main mono modern. (I have never seen CO2 deformation in any of my containers as bad as a poorly tuned mono can get!)
The invitro Ziploc containers don't have such problems. The grain subs typically have less myc per area and a good proportion of overhead air. The lids can be used to 'tune' conditions but it's not complex, easily learned in the going flow of the practice as the user does it. (For instance, when I have a room with some good air movement in it the lids can end up being just cracked. In still air rooms they end up practically sitting on the threads, which should only be done when known that the containers won't lose their moisture.)
These conditions simply are not enough to cause a negative change in mushroom growth. Macro morphology is still well within proper Cubensis growth, and yields per substrate are definitely not stunted. If any particular genetic set might happen to grow taller in conditions that retain more moisture and CO2, then fine. Good, even! I've had some shorter strains that grew larger invitro due to more retained moisture, warmth, and CO2. It was clearly caused by the conditions but was far from a problem. These two containers were the same isolate strain, for instance.
 
   See how the stems are longer, but barely fuzzy? The conditionsay have effected the fruit's appearance, but possibly for the better, and there aren't even signs of fuzzy stems which many people here say is a sure sign of too little FAE (I disagree). The bottles are significantly taller than the Ziploc quart containers, and their caps are tiny and don't allow much air exchange so high up there. Yet still the growth isn't problematic, even at less air than the normal invitro containers provide!

Very nice. Thanks for the explanation.
Now what bags do most people use, to go over the mouth of the container, like the one in the pic you posted. That doesn't look to me like a standard, large ziplock bag. I know it would vary from container to container, but is there some agricultural or gardening bag that I should know about? It looks like its made for the container, no tape or zip tie holding it on.

That's actually a 2L soda bottle. I cut it at the widest point and slip it over the threads of pint containers. I find it easier than baggies, and it's re-using, the ultimate recycling. They can be with caps all the way loose, or better yet with just a touch of poly, or even completely open if conditions don't make it a problem!

I'm afraid I don't understand this sentence. The part about caps, I'm guessing you mean cut the bottom off the soda bottle and use the cap for GE or FAE?
And I'm not sure what poly is. Like polyfill? And how could you ever leave it completely open? Like if you had a humidity controlled room?
